LOS ANGELES (TheBlaze/AP) — iPhone users that have been patiently holding out for Sept. 10 before upgrading in the hopes of a new model have something else to get excited about: a trade in.

Apple announced it will now join others in allowing you to trade in your old model.

The company said starting Friday that it would give customers credit for functioning older models at Apple Stores. The credit can be used toward the purchase of a new iPhone, which will be activated in the store. CNBC reported that customers would need to “leave store with new contract” to participate.

“iPhones hold great value. So, Apple Retail Stores are launching a new program to assist customers who wish to bring in their previous-generation iPhone for reuse or recycling,” Apple told Wired in a statement. “In addition to helping support the environment, customers will be able to receive a credit for their returned phone that they can use toward the purchase of a new iPhone.”

It didn’t say how much older phones would be worth. But other brokers such as Gazelle.com offer anywhere from $10 for a working iPhone 3G to $350 for an iPhone 5 that is in pristine condition.

Similar trade-in programs are run by retailers including Best Buy, Target and Radio Shack.

On Sept. 10, Apple will host a media event where it is expected to unveil a new iPhone, speculated to be called the “5C.”
